You want to add records when you're away or you want to edit the schema? If you only add records when you're away then you should have the db on the server import the records you add when you get back. If you've changed the schema you likely know what to do since you're working with a server and served files. Otherwise get some help.
Might it be possible to set up remote desktop access to your work computer?
Then you can work with your databases almost as though you were sitting in front of your computer at work.
